While Apple confirmed that purchasing a new AWS-enabled variant of the iPhone 5 was necessary to get on T-Mobile’s network, a new jaibreak hack claims to enable LTE at 1700mhz by loading a custom carrier firmware on an existing, unlocked AT&T iPhone 5 (A1428). Leimobile.com posted the full instructions:

Now that you have an unlocked AT&T model A1428 or an officially unlocked model A1428 you can proceed to follow the instructions below to load a custom carrier file onto your iPhone and enable LTE. This will only work on A1428 model iPhone 5′s.

To be clear, this enables LTE AWS support for T-Mobile. It won’t allow you to access HSPA+ 42Mbps on 1700mhz like Apple’s new A1428 variant…

T-Mobile officially unveiled on Tuesday its plans to carry the iPhone on its new no-contract, no-subsidy, monthly installment plans starting at $99 down for the iPhone 5. Following the announcement, Engadget confirmed with Apple that the existing A1428 model iPhone 5 for AT&T would not support the necessary AWS bands to access T-Mobile’s network. Apple said it would phase out the existing A1428 iPhone, meaning new devices would support both AT&T and T-Mobile, but it will be doing so through a firmware update at the factory. In other words, a software update for A1428 iPhone owners isn’t possible and existing AT&T iPhone 5 owners are out of luck when it comes to support on T-Mobile’s network.

The hack above, which we haven’t tested first hand, of course won’t work for the Verizon iPhone, as it does not support the correct LTE bands.

Yesterday, iOS hackers Conrad and Chpwnexposed the upcoming panorama mode in the iOS camera app that we previously revealed. While you can enable it a little easier by using the jailbreak tweak available on Cydia, for those of us who don’t jailbreak, Funky Space Monkeyshows us how to do it. We followed the steps, and it works just fine!
